Nvidia will feel enough pressure (likely from the ML / HPC space?) to provide open kernelspace support that they’ll actually make that happen.
Which… Has already happened.
Nvidia took a lot of the kernelspace logic that used to be in their proprietary driver, re-architected their GPUs to move that logic into a firmware blob (GSP).
And last year they released a completely Free driver that intefaces with GSP.
This allowed Nouveau developers to finally access critical features like power management (which were basically behind a wall of DRM, as Nvidia used legal and technical measures to lock Nouveau out of their firmware).
Now Nouveau has a new shader compiler, Vulcan support is growing rapidly, and people like me will soon prefer the Mesa stack for Nvidia over Nvidia’s own drivers.
And you can bet that Nouveau will work great with all of the Wayland compositors.
This is really the exact wrong point in history to be making the argument you’re trying to make 🤣.
